The platform was groundbreaking at the time and the Sidekicks, from the early black and white models to the full-color roller-ball models that appeared just before the launch of the Android-powered HTC G1 that essentially spelled the end of the feature phone.

That is not to say the Sidekick was a feature phone. As DeSalvo notes, this phone had a real TCP/IP stack, web browser, powerful text handling systems, a microblogging setup, and an app store and OTA updates before Samsung was aware that the mobile Internet existed. One of the most important features, however, was IM. DeSalvo writes:

Multi-Protocol Instant Messaging—we included an IM client(AOL Instant Messenger, Yahoo Messenger, MSN Messenger). We had Jabber support early on (the technology that Google Talk is based on) but we never shipped that. I don’t recall why. You could have up to 10 chats going at once and use the shoulder buttons to rotate between them, or chord the menu button and the number row on the keyboard to jump directly to a specific chat. It supported graphical emoticons and everything. We couldn’t use the full set of Emoji images back then because they were still under copyright from SoftBank in Japan, but we had pretty good coverage of the smileys that most people used.

The Sidekick died in July 2010 and its services were terminated a year later. A massive outage in 2009 reduced consumer trust in the service as millions of photos and other data disappeared completely. It was a mess. But the Sidekick could have been a contender. DeSalvo writes that they even approached Nintendo about offering a mobile-enabled Game Boy using the Hiptop platform. The plan was to allow OTA downloads of Nintendo games which, surprisingly, Nintendo’s licensing terms did not allow. This chimera could do some amazing stuff.

This led us do the following demo: start a Gameboy game and be watching regular Gameboy video. Then you’d receive a phone call and the Gameboy game would magically pause, and a hiptop alert window would display over top of the Gameboy video asking if you wanted to answer the call. As soon as the call was over the game would resume.

Nintendo passed on the technology.

The last Sidekick appeared in 2011 but it ran Android and was a Sidekick in name only. By that time all of Danger’s hard work had spiraled out into the rest of the ecosystem, leaving a legacy of solid mobile interfaces and some amazing memories. DeSalvo’s piece is a great walk down memory lane and definitely worth a read.
